DIRAIM EQUALIZlE-Rv Application filed December 16 1916.

To all whom it may concern:

Be it known that T, JIM P. Bu'r'rs, a citizen of the United States,residing at Carbon, in the county of Eastland and State of Texas, haveinvented certain new and useful Improvements in Draft-Equalizers, ofwhich the following is a specification.

This invention has relation to draft equalizers, and has for an objectto provide a device of this character adapted to be secured to the drafttongue of an agricultural machine such as a binder whereby the machinemay be drawn evenly and in a straight line, irrespective of theresistance which may be applied unevenly to the sides of machine due toits operation, and whereby the draft animals may be suitably disposed ateach side of the draft tongue and hitched to the equalizer to insureuniform travel of the machine.

In addition to the foregoing my invention comprehends in'iprovements inthe details of construction and arrangement of parts to be hereinaftermore fully described and particularly set forth in appended claim.

In the accompanying drawings in which similar and corresponding partsare designated by the same characters of reference throughout theseveral views in which they appear:

Figure 1, is a view in plan of a draft equalizer, constructed after themanner of my invention, and illustrating its application to a drafttongue and Fig. 2, is a transverse section taken on the line 22 of thepreceding figure.

With reference to the drawmgs 1 indicates a draft tongue of conventionaltype and 2 indicates generally the draft equalizer applied thereto.

This draft equalizer includes a pair of superposed frame bars 3 disposedtransversely of the tongue and secured to the upper side thereof throughthe medium of a U-shaped bolt 4 which extends beneath the tongue withits terminals 5 projecting upwardly at each side of the tongue andthrough openings provided in the frame bars 3 for the reception of thesaid terminals. Nuts 6 are applied to the threaded terminals 5 of theU-bolt whereby the frame bars may be secured to the tongue and suitablespacing blocks 7 are disposed between the bars 3 to dispose them inspaced relation for a purpose which will be resently obvious.

The frame bars 3 are ent downwardly at Specification of Letters Patent.

Serial No. 137.379.

an angle from a point adjacent the ion 'itudinal edges of the drafttongue as set orth in. Fig, 3 and pivoted between the outer ex trcmities f said bars at either end thereof is a. lever indicated at 8. Eachlever is pivoted at substantially a point intermediate its ends to theends of the bar 3 through the medium of a rivet bolt or the like.indicated at 9.

Mounted on the draft tongue forwardly of the equalizer is a bracket 10constructed of strap iron having an attaching portion whereby it may besecured to the tongue and a rear portion ll spaced vertically from thesurface of the tongue to receive between the under side of the saidsurface and the tongue a pulley 12 mounted for rotation upon a bolt 13which passes through said portion 11 of the bracket and the tongue. Aflexible element 14 which may be in the nature of a cable, section ofchain or the like is passed partly around the forward portion of thepulley l2 and is connected at its terminals to the inner adjacent endsof the links 8 through the medium of a series of perforations 15provided in said ends of the levers. Thus. the ends of the flexibleelement may be secured in any of the perforations with a view to varyingthe leverage of the levers 8 for the purpose of evening the draft. Tothe outer ends of the levers 8 are secured swiugletrees 16 forming ameans for hitching thehorses or other draft animals thereto.

Thus, it will be seen that with the flexible element connected to thelevers 8 in the manner set forth in Fig. 1 of the drawings the draftupon the machine will be more or less even. However, should it bedesired to provide a greater draft upon one side of the tongue than theother, owing to the uneven resistance to movement of the machine due toits operation, the terminals of the flexible element may be inserted ineither of the perforations 15 until the draft is evenly distributed.

While I have thus illustrated and described my invention with somedegree of particularity I realize that in practice various alterationsthereover may be made, and I therefore reserve the right and privilegeof changing the form of the details of construction or otherwisealtering the arrangement of the correlated parts without departing fromthe spirit of the invention or the scope of the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is:

In a draft equalizer, the combination of a draft tongue, 11 frameincluding a pair of superposed plates extended transversel of the tongueand secured thereto in space relation, the ends of the plates being bentdownward at an angle to the vertical, a pair of levers, one on each sideof the tongue ivotally mounted between the outer ends 0 the plates atpoints intermediate the ends of the levers, a pulley mounted on thetongue, a flexible element passed around the pulley and having its endscomiectcd to the inner ends of the levers, and wliililetrees connected15 to the outer ends of the levers.

In testin'iony whereof I allix my signature in presence of twoWitnesses.
